Description

METHOD FOR DISCRIMINATING REVISION OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM, AND SYSTEM TO THE SAME}

The present invention relates to a wireless communication system, and more particularly, to a method and system for identifying a revision of a terminal in a wireless communication system.

Mobile communication networks are evolving in the order of IS-95A, IS-95B, CDMA2000 1x, CDMA2000 1xEV-DO, CDMA2000 1xEV-DV, and WCDMA.

The IS-95A / B network separated voice and line data at the exchange, and provided service by changing the line data into packet data by an interworking device (IWF). The data transmission rate reached about 64 Kbps as it reached the IS-95B. .

In addition, in the CDMA2000 1x network, a data core network (DCN) was introduced to support high-speed data services, and a packet data service node (PDSN) was connected to the Internet, and data reception was introduced by the introduction of a home agent (HA). Mobility management has been made possible, and data transfer rates have reached up to 153.6 Kbps.

Meanwhile, CDMA2000 1xEV-DO network is a packet data dedicated network that supports the highest data transfer rate of 2.4576Mbps. It is implemented together with CDMA2000 1x system to provide voice service by CDMA2000 1x and share data core network with CDMA2000 1x. -Has a terminal authentication function by the authentication device (AN-AAA), and has a function of managing the terminal location by the data location register (DLR).

As such, the CDMA2000 1x service is a service capable of wireless Internet at a much higher speed than the speed supported by the IS-95A / B network by using the IS-95C network that has evolved from the existing IS-95A / B network.

The CDMA2000 1xEV-DO system began with Qualcomm's announcement of a technology called IS-95 HDR, which is identical in frequency to the CDMA2000 1x, but a completely different radio access standard for other modulation schemes.

Although HDR technology adopts the CDMA scheme, in order to provide a packet data service, a modulation scheme of a signal is adopted in a completely new format to implement a kind of TDMA function on the forward link.

This has attracted attention by providing a maximum data rate of 2.4 MHz using the same 1.25 MHz frequency band as the IS-95.

Specifically, the forward link of the CDMA2000 1x system transmits all channels multiplexed in the code direction so that the signals of all users are simultaneously occupied by all frequencies, while the forward link of the CDMA2000 1xEV-DO system only has one user at a time. The data is transmitted, and at the next moment, another user's signal is transmitted to form a multiplexed form of time division multiple access (TDMA) having a different signal transmission time for each user.

In this case, the base station can set the power of the transmission signal for each user to the maximum value of the base station transmitter, so that in the time zone occupied by each user, the base station can transmit the signal with the most suitable signal for each user. As a result, data rates up to 2.4576Mbps can be supported.

The CDMA2000 1xEV-DO system is now evolving from Rev.0, which was commercialized in 2002, to Rev.A, which is currently being commercialized.

 Rev.A is the original 1xEV-DO Rev. In addition to providing a higher peak data rate by upgrading only the channel card, the system also includes higher quality services, such as QoS, which was not implemented in Rev. 0. Provide infrastructure.

Under the present mixed system of 1xEV-DO Rev.0 and Rev.A, one of the important things from the service operator's point of view is how much quality the service currently provides.

For this quality analysis, the system collects various job data, and the most important of them is statistical data collected each time a call ends.

However, in the case of 1xEV-DO Rev. A, since the identifier that can be distinguished from Rev. 0 is not defined in the standard, the statistics of Rev. A are included in Rev. 0 and collected.

That is, in the conventional CDMA2000 1x service, an identifier for identifying each user according to a standard revision is used as a protocol revision.

For example, in case of protocol revision 6, 1x Rev.0 user In case of protocol revision 7 or more, it means 1x Rev.A user. Therefore, there was a basis for separately collecting statistics for each revision according to the needs of network operators. .

However, in the case of 1xEV-DO, since there is no identifier for distinguishing Rev. 0 and Rev. A, there is a problem in that there is no method for collecting / analyzing the network quality of Rev. A separately.

This problem occurs as the wireless communication network standard evolves from version to version, and is not a problem in the CDMA2000 1xEV-DO system but also in other wireless communication systems such as a WCDMA system.

There is a need for a solution to this problem.
